TYPEWRITING MACHINE.

Application filed March 26, 1924. Serial No. 701,913.

To all whom it may concern:

Be it known that I, Jnssn A. B. SMITH, a citizen of the United States,residing in Stamford, in the county of Fairfield and State ofConnecticut, have invented certain new and useful Improvements inTypewriti a web composed of several plies may have the platen beingswung up to release the',

successive forms or bills printed thereon, said plies being interleavedwith carbonsheets and fed around a cylindrical platen,

web, to facilitateshifting of the carbonsheets to a fresh portion of theweb.

More particularly, the invention relates to' tally-strip or record-sheetfeeding mechanism to be used in such'machines. In In co-pendingapplication No. 696,556,. filed March 3, 1924, provision is made tolinea space a tally-sheet once for each bill-length, so that the namesor items appearing on the successive bills may be copied in condensedform on the tally-sheet.

An object of the present invention is to line-space the tally-sheet foreach line-spacing operation of the bill-sheet, so that all of the itemstyped on the bill are copied on the tally-sheet. Preferably these itemsare copied in condensed form on the tally-sheet. For example, the itemscopied on the tallysheet may bearranged at single line-space intervals,while the items on the bill-sheetmay be arranged at two or threeline-space intervals.

A'take-up roll or receiving roll is provided to feed the tally-sheet,the leading end of which is connected to said take-up roll. Said take-uproll is connected with the platen line-spacing mechanism to enable thetally-sheet and the bill-sheet to be linespaced simultaneously by theactuation of the regular line-space handle. To this end the platenline-spacing mechanism comprises the usual line-space slide which issupported on the platenframe, and the tally-strip line-spacing mechanismcomprises a linespace slide "which may be supported on thecarriage-frame, and there is secured to one of said slides an .armextending to the other slide, to connect said slides, so that saidslides may be operated simultaneously. Since the platen line-s acingmechanism is carried by the platen-firame and the tallysheetline-spacing means is supported on the carriage-frame, provision isherein made by means of a slot in-said connecting arm to enable theplaten line-spacing mechanism to be freely shifted relatively to thetally-sheet line-spacing mechanism during case-shifting movements ofsaid platen.

A feature of the invention relates to the connection from the platenline-spacing mechanism to, the take-up roll for the tallysheet, which isconstructed to enable the swing-frame to be freely o erated to swing theplaten in order to facilitate the shifting of the carbon-sheets. To thisend, the takeup. roll has secured thereto a ratchet-wheel which formspart of its line-spacing mechanism, and which may be swung away from arelatively-fixed co-operating pawl when the platen is so actuated.

'Another feature of the invention resides in the provision of acarbon-sheet for the tally-sheet or strip, which may be connected to theregular carbon-carrier of the continuous billing machine, so that it maybe retracted with the carbon-sheets interleaved between the-plies of thebill-web.

In order to condense the items copied on the tally-sheet, thetally-sheet is usually fed slower than the bill-sheet, and it is commonpractice to feed the tally carbon-sheet at the same speed as thetally-sheet. If the tally carbon-sheet were fed at the same speed as thetally-sheet in-the present machine, however, in which the tally-sheetalso moves at a'slower speed than the bill-web, and in which, it will beremembered, the tally carbon-sheet is connected to the carbon-carrier,which travels at a faster speed than that of the tally-sheet, the tallycarbon-sheet would buckle or pile up behind the platen, because its rearend would be advanced faster by the carbon-carrier than its forward endis advanced by 'means of the take-up roll. Another feature of theinvention is to prevent buckling of the tally carbon-sheet. To this endit is fed faster than the tally-sheet, preferably at the same speed asthe bill-web, and consequently at the same speed as the carbon-carrierto which it is connected. For this purpose, the tally carbon-sheet ismade relates to means'to overcome this tendency.

To this end there is provided a friction device, which is referablylocated behind she platen and is e ective to engage the tallysheet, tothus prevent said tally-sheet from being accidentally advanced at anundesired speed.

Other features and advantages will here-' inafier appear.

In the accompanying drawings, Figure 1 is a side elevation, showing thecarriage of a continuous billing typewriting machine, with my inventionapplied thereto. Figure 2 is a fragmentary top plan riew of the partsshown in Figure 1.

Figure 3, is a diagrammatic side View, showing the parts in positionwhen the laten is swungup to release the work-web to facilitate theshifting of the carbon-sheets.

Figure 4 is a diagrammatic front view,- showing the arrangement ofbill-web, tally-.

sheet and the carbon-sheets with relation to each other, and also withrelation to the feederollers.

Figure 5 is a View similar to Figure 4, but shows another arrangement ofthe tally- .sheet with relation to the work-web and the feed-rollers.

The invention isshown applied to an Underwood continuous billing machinein which type-bars 10, when operated by l-ieys (not shown), swingupwardly and rearwardly to print against the front of a cylindricalplaten 11. The platen is mounted in a platen-shift-f'rame- 12, which issupported in a carriagre-frame 13 for caseshifting movements, to enablethe platen to be brought into co-operative relation with lower-casetypes 14" or' upper-case types "15 on the type-bars.

A web-supporting table 16 extends rearwardly from the platen, over whicha: composite work-web 17 may be advanced from any suitable source ofsupply to the platen to be typed'upon, said composite web being composedof separate plies 18 with carbonsheets- 19 interleaved between them, and

which maybe fed around said platen by feed-rolls 21 hearing against theunder side thereof. -The table 16 is connected to ihe carriage-frame 13in )the usual way by brackets 20 secured to said carriage-frame totravel. with thecarriage during letterspacing movement s thereof, saidtable being guided in "the usual way, as shown in the Wernery & Smithpatent above referred to.

The carbon-sheets are'attached, .at theirrear ends, to individual bars22 on a carbon-ear rier 22, which is mounted on the web sup? portingtable 16 in a manner to be moved f back and forth on said table, or, inother -words, towards the platen,-with the carbonsheets 19 while thecomposite web is fed around the platen and away from the platen in orderto shift the carbon-sheets to afresh portion of the. composite web. The

composite web. may beprovided with 1"egu.-' I

lar forms or bills of equal length printed thereon, as is wellunderstood in the art, and n after'a bill or set of superposed bills hasbeen completed, the carbon-sheets 19 are retracted or shifted to asucceeding set .of bills by means of the carbon-carrier, which isactuated by a handle 23 and arrested by I an adjustable stop 24.- Thebill-web 17 is thenpulled forward against a gage 23 on 'a gage-bar 26 toposition the typed set of bills prior to severing them from the web.

To facilitate the shifting ofthe carbonsheets and the'gaging ofthe typedbills, the

platen may be swung upto an abnormal position, shown in Figure 3, toenable the web to be straightened out, so. that, the-carbonsheets may bereadily -shifted relatively ported ina swing frame 27, Figure 1,pivotally mounted at 28 in the platen-frame 12, in a manner similar tothat disclosed in the thereto. For this purpose, the platen is sup--application of -William' F. Helmond, Serial I.

No.1 609,560, filed December 29,- 1922.

The platen line-spacing mechanism may include a line-space wheel 29,which may be connected to the platen, as in said Helmond application, toenable the swinging move- ,ment of said platen. The line-space wheel isoperated by a spring-pressed pawl 29 pivotally supported on a line-spaceslide 30 suitably supported on the platen-frame 12,

said slide being actuable by. the usual linespace handle (not shown)against the ten- .sion ofa return spring 3 l.

A record-sheet or tally-sheet 32 is provarious bills are copied. Therecord-sheet is fed from any. suitable source of supply, which may belocated at the back of ,the machine, and is conducted over the webtable16 and the carbon-carrier thereon, and then downwardly at the front ofsaid table with the bill-web 17 towards and around said platen past theprinting point.

It is desirable to have the items copiedon the tally-sheet in condensedform. Consequently there is provided means which may comprise a separateline-spacing mechanism for said tally-sheet, so that it. may

saidplaten, and upwardly at the front of' 1 15 'vided, upon which theitems typed on the be fed slower than the bill-web. To this end, theleading edge of the tally-sheet 32 is secured to a take-up roll 33 fixedto a shaft 34 revolubly supported in brackets 35 secured to theplaten-swing-frame 27. The shaft is provided at one end with aratchet-wheel 36 to be actuated to revolve the shaft, and consequentlythe roll 33thereon, in a clockwise direction by a springpressed pawl 37supported on a slide 38,

which may be reciprocated in a bracket 39' secured to one of thetablesupporting brackets 20.

Connection between the tally-sheet linespacing slide 38 and the platenline-spacing slide 30 is made so that they may be operatedsimultaneously by the actuation of the usual line-spacing handle (notshown), which engages the platen line-space slide 30. Said connectionmay comprise an extension or arm 40, which is herein shown secured tothe platen line-space slide 30, and which extends upwardly to therecordsheet line-space slide 38. Said armhas at its upper end a slot 41to receive a lateral extension 42 on said slide 38 to connect it withsaid slide. It will be noted that the platen line-spacing mechanism'issupported on theplaten-frame, which, it will be remembered, is shiftablefrom lower-case position to upper-case position, and that the line-spaceslide 38 for the tally-sheet is supported on the carriage-frame 13,which is relatively fixed. Consequently provision is made by extendingthe slot 41 downwardly in said arm 40, to enable the arm to be shiftedwith the platen relatively to the line-space slide 38 which it operates.

The platen line-space slide 30 always moves through the same lineardistance, as

' in the Underwood machine, irrespective of the number of line-spacesimparted to the platen by each operation of said slide,t he

line-spacing mechanism being settable by a line-space control-lever 43,to enable the platen to be line-spaced one, two or three line-spacedistances at each actuation of the line-space slide, according to thesetting of said control lever. Said control lever is connected to apawl-controlling element 44 having a shelf 45 thereon over which anextension 46 of the line-spacepawl rides,

arm 40 is to one side of the bracket 39 (Figure 2), so that not to beobstructed in its movement by said bracket.

It will be understood that the relation between the line-space wheel 36,associated with the take-up roll 33, and its co-operating line-spacepawl 37, is such that said linespace wheel may readily be swung awayfrom the pawl during a platen-swinging operation, and when the platen isagain lowered to its typing position that the linespace wheel is broughtback by the swingframe into effective relation with the linespace pawl.

A carbon-sheet 47 is provided for the tally-sheet, said carbon-sheetbeing connected at its rear end to a carbon-blade 48 supported on thecarbon-carrier 22, so that said carbon-sheet may be retracted, with theother carbon-sheets 19, to a fresh portion of the tally-sheet at eachcarbon-displacing operation. Since the tally carbon-sheet 47 isconnected with the carbon-carrier 22,.which movesat the same speed asthe bill-web 17 and faster than the tally-sheet 32, it is desirable tofeed the tally carbon-sheet at the same speed as the bill-web, andfaster than the tally-sheet, to prevent buckling of said tallycarbon-sheet 47, which would ordinarily occur, in the present machine,if the tally carbon-sheet were fed at the same speed as the tally-sheet32.

To enable the tally carbon-sheet 47 to be fed with the bill-web 17, itextends considerably beyond the right-hand edge of the tally-sheet 32(Figure 4), so that it may be fed by means of the feed-rolls 21, whichare located to one side of the tally-sheet 32, 'so that the latter maybe fed independently of the bill-web. The tally-sheet may be located inthe middle of the bill-web, as shown in Figure 5, instead of thelefthand end thereof, as shown in Figure 4, and in which case thefeed-rolls 21 are arranged one near each side of the billweb. 17 andbeyond the sides of the tallysheet 32.

Since the tally-sheet is nearest the platen, there may be suflicientfriction caused by the bill-web at times to tend to advance thetally-sheet at the same speed as the billweb, which Wouldbeobjectionable since it is desired to feed the tally-sheet at a slowerspeed in order to condense the typed items thereon. To overcome any suchtendency, however, there is provided a friction device comprising aspring-pressed bar 50 cooperating with a bar 51 secured to thewebsupporting table 16 by screws 52, the'tallysheetpassing between saidbars. It will be understood that this friction device will not interferewith the adavancement of the tally-sheet around the platen since saidtallylOl up roll 33 to which, it will be remembered,

, the leading end of the record-sheet is atspacing mechanism comprisinga line-space wheel on said swing-frame for the recordtached.
